Hasta La Gadget!

Some tablets and smartphones ship with an AMOLED display. Newer ones are shipping with a “Super AMOLED” display. What so super about it, and what does all this alphabet soup even mean?

The short version is that a Super AMOLED touchscreen display integrates touch sensors with the glass surface panel, eliminating at least one layer of glass and with it, a layer of air. That’s what makes Super AMOLED super. Only Samsung makes it.

I said “at least one layer of glass” because AMOLED itself eliminates at least one layer in a display. The current Galaxy Tab, for example, uses a TFT-LCD (Thin-Film Transistor Liquid Crystal Display) screen. Until very recently, TFT-LCD has been the state of the art in thin color displays and is still the only cost-effective option in the vast majority of displays larger than a smartphone screen.

TFT-LCD has approximately four layers: a backlight, a TFT color filter, a touch sensor panel, and an outer glass screen. AMOLED (Active-Matrix Organic Light-Emitting Diode) eliminates the separate backlight. AMOLED, however, is known for having problems with glare and readability in direct sunlight, even relative to average LCD screens. By minimizing the number of reflective surfaces and power necessary to achieve vivid color, Super AMOLED was designed in part to address this.

Samsung introduced Super AMOLED to commercial devices this year with the Samsung Wave, which ran their own Bada OS. The Android-powered Samsung Galaxy series of smartphones made the displays popular, and it’s since appeared on Samsung’s Windows Phone 7 handsets as well.

There are other advanced color technologies in the market, all of them super, and all of them extra-expensive: Super LCD recently joined Super IPS and Advanced Super View. But only Super AMOLED has really captured the popular imagination.

A 7-inch Android tablet with an AMOLED display would probably be a serious advance over its current LCD screen. But if it’s “just” AMOLED, something about it would just seem… less than super.

For all intents and purposes, every single flexible display we’ve seen over the past few years has eventually been filed in the “awesome things that’ll never materialize” drawer. There are exceptions to that rule, mind you, but we’ve largely been frustrated by how often these things pop up at trade shows and then vanish forever. Samsung Mobile Display, however, is hoping to change that. According to reports stemming from FPD International 2010, this here 4.5-incher is dangerously close to production, and given the lustworthy 800 x 480 resolution, we couldn’t be more excited about the possibilities. We’re told that Samsung is eschewing the traditional glass substrate in favor of a newfangled plastic version, and evidently it’s a heck of a lot easier to mass produce. After all, we’re still waiting for this thing, guys.

Hey, remember when Taiwan’s ITRI said that flexible TFT-EPD displays would be ready for smartphones by 2009? Yeah, well, keep that in mind when reading about this new 6-inch flexible display the company says will be released in a line of e-readers “very soon.” It’s called the FlexUPD, a 1mm thick AMOLED with a 5cm folding radius, 150nits brightness, and “unbreakable” construction. ITRI is also talking up its switchable 2D/3D display that we saw earlier, able to display both types of content simultaneously and do so without the requirement of goofy glasses. That tech is called i2/3DW and is set to “revitalize the [display] industry by revolutionizing the concept of 3D viewing.” You keep on believing, ITRI, we’ll just keep on waiting.

To say we’ve been eagerly anticipating the Dell Lightning would be an understatement along the lines of suggesting Microsoft’s launching a few Windows Phone 7 devices today. Dell’s AMOLED-equipped WP7 debut has just gone official with a cringe-worthy renaming to the Venue Pro for T-Mobile, who has in turn announced its intention to carry the 4.1-inch portrait QWERTY slider “in time for the holidays.” Notably, you won’t be able to purchase the Venue Pro directly from T-Mo stores, as Dell and its choice of handpicked retailers are set to handle the purchasing experience. Don’t look for any AT&T hookups, either — Dell has acknowledged T-Mobile as its “launch partner” for the device, giving team Magenta a second major exclusive, even if this one doesn’t last much beyond the launch period. Needless to say, we’ll seek to confirm the full spec sheet as soon as we can, though the officially known 1GHz Snapdragon chip and 5 megapixel imager agree with the Lightning’s original leak. For more on the fresher than fresh Dell Venue Pro, check out our hands-on pictures and impressions.

If you’re a numbers geek, you’re trying to be scientific about your next smartphone purchase, or you just like pretty colors, you might appreciate DisplayMate’s latest report rounding up examples of all (well, most) of the latest and greatest display technologies out there: IPS LCD, Super AMOLED, AMOLED, and TFT, represented by the iPhone 4 and Droid, the Galaxy S, the Nexus One, and the iPhone 3GS, respectively. Noticeably missing is SLCD, the technology HTC has been using to make up for lost ground on its AMOLED shortage from component supplier Samsung, but we’ve got a hunch DisplayMate’s hard at work at adding that into the mix.

Anyhow, considering the sheer number of variables the firm takes into consideration — everything from color depth, to brightness, to reflectance, to color gamut — there’s no clear-cut winner, but the Droid and iPhone 4 are obviously a cut above the rest with generally higher scores and better performance across the board. The Galaxy S’ Super AMOLED turns in a decent performance, too, but takes a little hit for its 16-bit color depth and blown-out colors. Of course, if you consider any of these — even the crappy TFT on the 3GS — to a phone from five years ago, it still looks like science fiction… so you really can’t go wrong, can you?
